My invention .refers to an improved construction in metallic cars, more particularly hopper-bottom cars; and it consists in the features of construction as shown in the drawings and as hereinafter described.

The invention has in view the cheapening,

strengthening, and simplifying in construction of what are known as steel cars, more particularly dumping cars, by the use of standard rolled sections -of structural steelsuch as cl1annels,&c.with portions compris- 'Vides an end platform for the oar.

ing the elements of the framing structure consisting of plate-partitions, bracing and supporting members, a series of individual doors, and the means for supporting and operating them, as shown and described.

Referring to the drawings, 2 2 are the center sills, made of structural shape, as channels, midway Of the main framework, running longitudinally for the full length of the car, assembled in close relation to each other and with sufficient intervening space to receive draw-heads 3, with their accompanying draft-gear, at each end. On each side, on correspondinglevels with thecenter sills, are the side sills l of suitable structural shape, as channels or I-beams, with which center sills and side sills are incorporated the end sills 5, likewise of similar structural members, incorporated with the side and center sills by suitable angle-brackets riveted to each, so as to properly secure the parts together in the manner customary in structural work'. Across the ends of the foundation structure from side to side above and below and secured to the center and side sills are the reinforcing end-sill members 6 (5 of suitable form, as

channels, which serve to bind these parts securely together, giving a finished appearance, while the upper one of such members pro- At the corners are located the post members 7 and 8,

of channel or other structural form, secured Y to the side and end sills and providing means for attachment and support of the sides 9, of plate metal, andalsoof the ends lO of the car, which posts, sides, and ends maybe of any height desired. the full depth or maybe extended down to the upper ends of downwardly and inwardly inclined floor-plates 11,secured to the framework and constituting the floor portions at each end of the car. If desired, 'such iioor portions may be laid flat upon thefoundation structure and conforming to the generalfloor-Y level of the car.

Midway of the car at each outer side, mounted upon and secured to the side sills, are vertical post members 12, while above the body-holsters, similarly mounted, are similar post members 13 of structural form, as chan- The ends lO maybe foi` i nels, all of such side posts, with posts 7, being connected with upper longitudinal reinforcing members 1l, of channel or other suitable shape.

The upper member 14C constitutes the upper portion of the side framework, to which framework is secured on the inside the sides O'of the car, preferably of plates.

Midway of the length of the car, running across underneath from side to side, are supporting-bolsters 15, secured to the underside of the framework in any suitable manner, which project outwardly at each side sufficiently far to engage the supporting trussrods 16, which bear under and support the bolster and middle portion of the car, intervening shoes 17, secured to the holsters, being preferably employed to provide suitable bearings for the rods.

The rods 16 are deflected upwardly and are secured to the body-bolster posts 13 at each end by passing through the flanges thereof and secured by nuts or in any other suitable manner reinforced by a supporting anglebracket underneath, and as thus arranged the rod constitutes a tension-truss at each side, by which the strain of the middle portion of the car is largelysupported from above the body-bolsters over the trucks.

Oppositely arranged to the truss-rods 1G, on each side, are the compression members 1S of structural form, as channels, bearing at the middle against the upper ends of posts 12 and underneath the top member 14 and sloping downwardly in opposite directions, bearing against the posts 13 at or above lthe point where the tension rods 16 are connected. These members 1G and 18 thus provide a diamond-shaped truss of great strength, stiffness, and supporting power, and when the side members of the car are thus arranged and connected together and with the side plates the resulting structure provides sides of great simplicity, few parts, and ample strength for the purpose in view. The sides are further reinforced by inner posts 19, midway of the car and at cach side of the middle position, with an intervening distance equalin g the width of the dumping-doors, hereinafter referred to, which posts are secured on the inner sides of the side sills 4 and to the intermediate cross members, which extend across at suitable intervals in the length of the car between the side and center sills and provide supporting e bearings for the door. These members consist of plates 2O 20, secured to the center and side sills, with sufficient intervening space for mounting the supporting devices for the doors, the tops of each pair of plates being covered by the anges 21 of T members, the web of which extends downwardly between the plates, as shown. The space between the web and the plates on each side is filled by suitable filler-blocks 23, the plates, filler, and web being connected at intervals by rivets or bolts 24.

At the point where the floor portions 11 terminate at their inner ends they are supported upon and aline with, crosswise of the car, similar single cross-plates 25, which may, however, if desired, be of other forni, as channels.

On the inside of the side plates f), connected to and further reinforcing them, arc the vertical posts 19, which are likewise connected with the cross-plates 20, and it will be seen that by such arrangement of cross-plates' the floor of the car is divided longitudinally between the cross-plate-dividing floor portion and the terminals of the permanent fioor portions ll into a series of intermediate openings or spaces. ln the construction shown these are four in number on each side, although such number may be varied, as desired and according to the objects in View. Extending downwardly and outwardly on each side of the center sills from the normal level of the floor at a suitable angle are inclined plates 26,while from the opposite sides, similarly arranged with relation to the side sills, are similar plates 27, slantin g inwardly. Such plates 2G and 27 constitute hoppers and provide reduced intervening longitudinal rectangular openin gs, which are covered beneath and closed by the shifting doors. In the form shown in the principal figures of the drawings these doors consist of plates 2S oi' dimensions adapted to cover the openings reinforced by lateral and intervening fianged members 29, through which passes a bar or shaft 30, supported between the cross-plates 2() on suitable swinging links or arms 31, as shown,the filler-block being suitably recessed for clearance. On each side the cross-plates are provided with angle members 32, which may be located at or slightly above the lower edge of the cross-plates at each side, against which flanges the doors are adapted to bear in their closed position. Each door is provided with an operating handle or leverl 33, pivotally connected with the door at 34E by a bolt. or rivet mounted in any suitable supporting-bearing, the operating-lever having stops 35 adapted to engage against the inner and outer sides of a` bearing stirrup or guide in the closed or open position of the door, respectively, and to hold it in said position. If preferred, the operatingdever may be jointed, as shown in Figs. 7 andv 8, the joint preferably being provided with shoulders or knuckles permitting it to open upwardly, but not downwardly, in which case the door may be forced back when closed, while the joint in the lever will permit it to drop down vertically at the side of the car out of the way when open, as shown in Fig. S.

In Fig. f) I have shown a modified construction of the door, in which the inner inclined floor 26 extends outwardly at a flatter angle, terminating nearer the outside of the car, while the outer inclined floor 27 is more abrupt, the results of which arrangement is that the space between such floor members is so disposed that the weight of the contents of IOC IIO

`the car will bear more directly against the floor members than against the door.

The door 2S consists of a plate of suitable dimensions to cover the intervening opening and is provided with a terminal bar pivotally mounted at 37 in bearings secured to the inner sides of the cross-plates, the door being stiffened or reinforced by an angle or suitable bracing member 38 and adapted to be opened and closed by the locking-lever 33 in the manner already described. f'

, In Figs. 14 and l5 a construction is shown in which the ends of the inclined floor-plate 26" and 27" are similarly disposed, but in which the outer plate 27 does not extend above the general licor-level of the car. In this construction the door 28 is pivotally mounted in the same manner as already described at 37 and operated by a similar bracing-handle. As shown, a series of such openings and doors is arranged along the floorof the carat each side of its middle portion, and as each opening is provided with separate independently-operated doorsthe contents of the car may be discharged at either side or at any point as to its length within the range of the series of doors. This is of considerable advantage in unloading various materials which will run out of the hopper-openings by gravity or which maybe shoveled to any particular opening.

AAs stated, the flooring ll may be inclined or iiat, as desired, and as thus constructed the car is capable of carrying` many varieties of freight-such as coal, ore, dac., in bulk, or lumber, rails, or other longitudinal bodieswhich may be loadedalong and upon the various rigid cross members and upon the permanent end flooring.

For the purpose of bracing the center of the cars from the sides I employ a truss-rod 3S,

passing through the side sills, as shown, and

secured by nuts, deflected at its middle portion downwardly and passing underneath'a block 39, adapted to support the center sills. If desired, the arrangement of the truss member 38 may be reversed, as shown in Fig. 13, in

which case the side sills are supported from the center sills, and it will be understood that either such forms of bracing may be adopted according to the uses for which the car is designed or as the under structure is arranged.

with relation to the body-bolster. Such brace members are preferably located at intervals across the car between the cross-plates and secure and rigidly b race and tie the various parts together in a strong and compact manner. As thus constructed my improved car is entirely composed of metal so incorporated as to provide simplicity and economy of construction with strength, durability, and adaptability to a wide variety of uses. The foundation structure, the sides, and ends -are well connected and braced, the strains are equally disposed throughout, while the doors and their manner of operation extend the adaptability of the car to a wide variety of applications and utilization.

Changes and variations may be made in the design, details, or other elements of the invention by the skilled mechanic; but all such changes are to be considered as within the scope of the following claims. v
